Science - Energy Flashcards
refers to the physical or mental effort exerted in order to accomplish a particular task or goal.
Work
is a device used to measure temperature.
Thermometer
refers to the internal energy of an object or substance that is due to the motion and vibration of its particles.
Thermal energy
To think deeply or ponder upon past actions, thoughts, or experiences, often resulting in insights or self-awareness.
Reflect
refers to a sustainable and environmentally friendly resource or energy source that can be naturally replenished and does not deplete over time.
Renewable
refers to the emission or transmission of energy in the form of particles or electromagnetic waves.
Radiation
is a facility that generates electricity by converting various types of energy sources into electrical energy.
A power station
refers to resources that cannot be replaced or replenished in a short period of time, such as fossil fuels.
Non-renewable
a simple machine consisting of a rigid bar that pivots on a fixed point, called a fulcrum, and is used to lift or move heavy objects with less effort.
A lever
states that energy cannot be created or destroyed, only transferred or transformed from one form to another.
The law of conservation of energy
is the energy possessed by an object due to its motion.
Kinetic energy
a unit of power equal to 1000 watts, commonly used to measure the rate at which electricity is consumed or produced.
A kilowatt (kW)
is the unit of energy in the International System of Units (SI).
Joule
is a material that restricts or prevents the flow of electricity, heat, sound, or other forms of energy.
An insulator
refers to the type of electromagnetic radiation that is situated between visible light and microwaves in the electromagnetic spectrum, characterized by longer wavelengths and lower frequencies.
Infrared radiation
a gas that traps heat in the Earth’s atmosphere, contributing to the greenhouse effect and global warming.
Greenhouse gas
refers to a set of mechanical components designed to transmit motion and power between rotating shafts, often used to increase or decrease speed or torque.
Gear
refers to hydrocarbon-based natural resources derived from the remains of ancient plants and animals, such as coal, crude oil, and natural gas, which are typically used as a source of energy.
Fossil fuel
refers to a state of balance or stability in a system where opposing forces or factors are equal.
Equilibrium
refers to the movement of fluids or gases due to the transfer of heat energy, resulting in the circulation or flow of the fluid.
Convective current
is the process of heat transfer through the movement of a fluid, such as gas or liquid, resulting in the transfer of heat from one region to another.
Convection
refers to the transfer of heat or electricity through a material or medium, typically through direct contact or particle collisions.
Conduction
is a facility used for the proper storage and handling of chemical substances, ensuring their safety and preventing potential hazards.
A chemical store
To take in or soak up a substance, energy, or information.
Absorb
